Ski, in particular alpine ski

ABSTRACT

A ski, especially an alpine ski, having a ski body with a shovel area forming a front end of the ski body, a rear ski body section forming the rear end of the ski body and in between these two sections, a reduced ski body section forming ski body longitudinal sides, in which the width of the ski body in the shovel area is greater than the maximum width of the ski body on the rear ski body section, and the maximum width of the rear ski body section is greater than the minimum width of the ski body in the reduced middle ski body section.

BACKGROUND OF THE INVENTION

The invention relates to a ski, in particular an alpine ski.

It is an object of the invention to present a ski with improved skiingcharacteristics that can be used universally, ensuring high stabilityand ease of turning.

SUMMARY OF THE INVENTION

The ski has a body with a wide width shovel area on its front end, areduced width middle section of the body and a rear section with a widthsmaller than the width of the front section but greater than the widthof the middle section. The difference between the maximum width of theshovel area and the maximum width in the rear ski body section is 25-31units, each unit being preferably 1 mm.

Due to a special form of the ski body and due to the resulting specialform of the longitudinal sides of the ski, the ski according to theinvention optimally combines the characteristics of an easy-turning skifor use in slaloms with the stability of an alpine ski.

BRIEF DESCRIPTION OF THE DRAWINGS

The invention is described below based on exemplary embodiments withreference to the drawings, in which:

FIG. 1 shows a side view of the ski embodying the present invention; and

FIG. 2 is a top view of the ski embodying the present invention.

DETAILED DESCRIPTION OF THE INVENTION

The ski generally designated 1 a in FIGS. 1 and 2, and all furtherembodiments of the ski according to the invention, designated 1 b-1 e inthe following, respectively comprise a ski body 2, which is manufacturedfor example using the standard ski construction materials, namely with afront, upwardly curved shovel area 3 forming the front end 2.1 of theski body 2, with a rear, slightly upwardly curved ski body section 4forming the rear end 2.2 of the ski body 2, and with a middle ski bodysection 5, which forms the binding area for fastening the binding to thetop of the ski body 2 and on which the ski body 2 is reduced on its twolongitudinal sides 2.3 to form what is known as the sidecut. Allembodiments of the ski according to the invention, as described in moredetail below, are identical with respect to the basic designcharacteristics of the ski body 2.

In the drawings, different dimensions b1-b3, l1-l6 designate the form ofthe ski according to the invention, as follows:

-   b1=maximum width of the ski body 2 at position A in the shovel area    3;-   b2=maximum width of the ski body 2 at position B in the ski body    section 4;-   b3=minimum width of the ski body at position C on the middle ski    body section 5, in which position C is somewhat closer to the rear    ski body end 2.2 than the front ski body end 2.1.

In addition to the above widths b1-b3 characterizing the special form ofthe ski body 2, different lengths l1-l6 characterizing the form of theski body 2 are likewise specified, as follows:

-   l1=total length of the ski body 2, i.e. the distance between the two    ski body ends 2.1 and 2.2;-   l2=distance between positions A and B;-   l3=distance of position A from the ski body end 2.1;-   l4=distance of position A from the transition between the middle ski    body section 5 and the shovel area 3;-   l5=distance between the ski body end 2.2 and position B;-   l6=distance between the middle M of the ski body 2 and position C.

The concavely curved or reduced longitudinal sides 2.3 of the ski body 2comprise a changing radius of curvature R1-R3, namely in the front partof the middle ski body section 5 adjoining the shovel area 3 the radiusof curvature R1, in the middle part of the ski body section 5 the radiusof curvature R2 and in the rear part of the ski body section 5 merginginto the area 4 the radius of curvature R3; it should be noted thatwhile in some embodiments the radiuses of curvature R1 and R2 areidentical, the radius of curvature R1 or R2 is larger than the radius ofcurvature R3 in all embodiments.

The values characterizing the special form of the skis 1 a-1 e aresummarized in the following table.

In the above table, D1 is the difference between the ski body width b1and b2 and D2 is the difference between the ski body width b2 and b3.Further, the values listed in the table are units, where one unitcorresponds for example to 0.9-1.1 mm, preferably 1 mm.

For all embodiments of the ski according to the invention, the width b1is always greater than the width b2 and the difference D1 between theabove-mentioned widths b1 and b2 is approximately 25-31, for example29.5-30.5 and preferably approximately 30 units, where one unit likewiseis 0.9-1.1 mm, preferably 1 mm.

The embodiment described above substantially improves the skiingcharacteristics of the ski 1 a-1 e, in particular also under differentskiing conditions or skiing styles, i.e. the embodiment of the ski bodyaccording to the invention has made it possible to optimally reconcilepartially contradictory requirements for ease of turning for example ofa slalom ski with the requirements for stability of an alpine ski.

The invention was described above based on exemplary embodiments. Itgoes without saying that further modifications and variations arepossible, without abandoning the underlying inventive idea upon whichthe invention is based.
